Liberty, Paul Wurth and SHS to develop hydrogen-based steel making plant

LIBERTY Steel Group, part of Sanjeev Gupta’s sustainable industry leader GFG Alliance, has signed a Memorandum of Understanding (MoU) with Paul Wurth and SHS – Stahl-Holding-Saar (SHS) to assess the building and operating of an industrial-sized, hydrogen-based steel making plant at Dunkerque in France. If developed, the plant would be one of the first operations of its type in France.

The pan-European partnership will work together on a project to incorporate a 2 million tonne Direct Reduced Iron (DRI) plant, with an integrated 1 GW capacity hydrogen electrolysis production unit, next to GFG’s ALVANCE Aluminium Dunkerque site. The DRI plant will initially use a mix of hydrogen and natural gas as the reductant to produce DRI and hot-briquetted iron (HBI), before transitioning to using 100% hydrogen once the electrolysis production unit is complete. The DRI/HBI produced will primarily be used in the electric arc furnace of LIBERTY Ascoval in France but any surplus will be used at LIBERTY’s Ostrava and Galati integrated steelworks as well as the SHS-group’s Dillinger and Saarstahl plants in Germany,

LIBERTY has been working with Paul Wurth and SHS on the technical and economic viability of the project since early last year. Now that initial feasibility work has proved successful the partners have signed a MoU which covers two phases:

• Phase 1 – will improve the accuracy of the project’s commercial and technical feasibility including the reducing gas mix, potential partners (energy supply, hydrogen production and operation, DRI/HBI equipment) and funding opportunities. This phase is expected to take around 12 weeks; and
• Phase 2 – deliver the level of detail required (technically and financially) for the effective implementation of the project. This phase will be determined as part of Phase 1.

Between them the partners are strategically focused on developing technology which will allow the steel industry to achieve its ambitious green targets, with LIBERTY undertaking carbon neutral programmes worldwide as part of its ambition to be carbon neutral by 2030.  Paul Wurth is a Luxembourg-based company, and member of the SMS group, which has a proven track record as a plant builder and service provider. Through its partnership with Sunfire, a German technology provider which develops high performance electrolysers for highly efficient hydrogen generation, Paul Wurth is looking to drive the maturity of this technology for industrial application. SHS – with both companies Dillinger and Saarstahl – is a highly regarded German steel producer. The SHS-group is dedicated to the goals of the Paris Climate Agreement and is committed to producing iron and steel with a reduced CO2 footprint. The partners will consider using other hydrogen producers as part of the project.

Commenting on the news, Sanjeev Gupta, Executive Chairman of GFG Alliance and LIBERTY Steel Group, said: “This project will realise the potential of steel and hydrogen working together to solve each other’s problems. Our industry needs to reinvent steel production fast, as the need to cut our emissions gets ever more pressing against a backdrop Liberty Steelof rising global demand for our products and legislative pressure to become carbon neutral. Hydrogen steel making has the potential to solve this issue and we’re determined to collaborate with like-minded partners to it make it happen. France is the ideal place to try, thanks to its strong industrial heritage, skilled workforce and low carbon energy infrastructure. Together with these technologically advanced and committed partners we are looking forward to exploring the potential for truly carbon neutral steel making, using green hydrogen to help us make GREENSTEEL products.”

Georges Rassel, Chief Executive Officer at Paul Wurth, said: “Paul Wurth is delighted and thankful to support LIBERTY Steel Group in its GREENSTEEL agenda. We are convinced that this project will contribute to paving the way for the urgently required technology switch in the metals industry.”

Martin Baues, Member of the Board of Directors for Technology at SHS – Stahl-Holding Saar, Dillinger and Saarstahl, said: “Despite the high hurdle of immense investment and operating costs, Dillinger and Saarstahl are determined to consistently pursue the path to climate neutrality. This partnership represents an important building block on the way to carbon neutral steel production and will help us to further reduce our carbon emissions on the basis of this technology and at the same time gain important experience in the use of hydrogen in steel production.”
